DRAFT-E QUALIZER.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed April 10, 1907. Serial No. 367,375.

To all whom it may concern.'

Be it known that I, JOHAN O. HELGEsoN, a citizen of the United States,residing at Soldiers Grove, in the county of Crawford and State ofWisconsin, have invented a new and useful Draft-Equalizer; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to a draft equalizer and the object thereof is toprovide a device of this design adapted for from four to eight or ten ormore horses; the different parts of the equalizer being so arranged asto success- .fully equalize the draft on each and every horse, anddesigned so as to bunch the horses close together.

The equalizer comprises a plurality of doubletrees and swingletreesconnected together by clevises and chains, as clearly shown in thedrawings. These chains may be or may not be so arranged as to cooperatewith pulleys, in lieu of fixed connections.

This invention comprises further objects and combinations of elementswhich will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claims.

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith, wherein Figure 1 is aplan view of the equalizer, illustrating the same adapted for use inconnection with ten horses. Fig. 2 is a view of a modified formillustrating the invention adapted for use in connection with eighthorses.

Making renewed reference to the accompanying drawings, wherein similarreference characters indicate corresponding parts in the severalillustrations,by figures, 1 designates an equalizer beam, that is themain beam which is designed for connection to the object to be drawn. Tothis beam 1 is connected a pair of supplemental equalizing beams 2 bymeans of clevises or chains 3, as clearly shown; to the outer ends ofthe beams 2 is connected a second pair of supplemental equalizing beams4 by means of clevises or chains 5. Each supplemental beam 4 is providedwith a pair of swingletrees 6 and 7, i

means of a clevis or chain 13. Carried by outer ends of the' beam 12 areclevises or chains 14 which connect with a pair of supplementalequalizing beams 15 to the outer ends of which the clevises or chains 16are connected, which connect with a pair of second supplementalequalizing beams 17, as clearly shown.

The supplemental beams 15, are provided with slots 15a in which slidingmembers 15b are mounted, as clearly shown in the drawings. Said beams15, are rovided with additional slots'15C dispose upon a plane at rightangles to the slots 15% and positioned in the slots 15C, are the staples15l which are carried vby Vsaid sliding members; these staples are forthe purpose of changing the position of the chains 14, which areconnected to the main equalizing beam as clearly shown. The said beams15 are provided with screwthreaded elements 15b, designed for thepurpose of holding the members 15b in adjusted position. Thisconstruction is for the purpose of regulating and equally distributingthe draft throughout the plurality of equalizers, as will be clearlymanifest.

'I'o equalize the draft, caused by the ull upon the beams 15 and 17, theinner en s of the beams 15 are provided with a chain connection 18,which is provided with a ring 19 to which a clevis or chain 20 isconnected, which has pivotal connection with an equalizing beam 21 whichin turn is provided with a pair of swingletrees 22, as clearly shown.

The pull, when this device is in practical use, upon the outer ends ofthe beams 2 is equalized by the pull upon the beam 12 which is connectedby the chain 10 to the beams 2.

The beams 17 are each provided with a pair of swingletrees 23, theconnection between which and the said beams 17 being obtained by theclevises or chains 24 and 25, as clearly shown in the drawings.

Fig. 2 illustrates a modification of the invention, in which anadditional set of equalizers are shown, and the swingletrees 6, 7 and 23are eliminated.

It is to be understood that various changes and modifications may beemployed in the construction and embodiment thereof, combinations offeatures, and elements, Without in any Way departing from the spirit andscope of the invention covered by t ie claims thereof; it beingunderstood that Whatever variations or modifications are employed mustfall Within the scope of the appended claims.

From the foregoing7 the essential features,

elements and the operation of the device, to-v gether With thesimplicity thereof, will be clearly a parent, and, when manufactured inaccor ance With the invention, an inexpensive market Will be easilyobtained there for.

Having thus fully described the invention, What is claimed as neW anduseful by the protection of Letters Patent, is

In a draft equalizer, the combination of a plurality of equalizersconnected in multiple, so as to equalize the draft on eight or tenhorses, chains for connecting the .equalizers in multiple, saidequalizers comprising main and supplemental equalizing beams, one pairof the supplemental equalizing beams having slots, sliding adjustablemembers positioned therein, said members having chain connection Withone of the main equalizing beams, said supplemental equalizing beamshaving screw-threaded members to hold the sliding members in adjustedposition and doubletrees having swingletrees connected thereto carriedby the said supplemental beams.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
